Here are some avitars I drew for an online RPG I play. And before you comment, yes, I know that they use the same pose more than once. That is because I cant do figure drawing. I get around this by tracing some forms I got a friend to draw me, and then adding the clothing/armor/weapons/color/etc.
Here are the ones I did for myself: My first avi for my charicter Dragonkin. My second Dragonkin avi. My current Dragonkin avi. My avi for my charicter Artemis.
Thats pretty good. Keep drawing and you will be able to master figure drawng techniques. You should also experiment more with shading, I have a feeling you would have fun with shading and find some very cool ways to shade.
